Vehicle Battery State Display with Pre-Notification Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle state display systems fail to provide adequate notification and user convenience when output limitations occur due to low battery charge, leading to confusing driving experiences and potential battery deterioration.
Innovation Solution
A vehicle state display device and method that includes an output limiting unit and a battery state display unit, which pre-notifies users of impending output limitations by switching through distinct display modes based on battery charge levels, allowing users to take proactive measures to avoid limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If output limitation is suddenly started when battery charge is low, then battery protection is achieved, but user convenience deteriorates due to confusion and inability to perform avoiding driving operations
Solution Approach 1:
The system performs preliminary notification by displaying a warning icon before output limitation actually occurs. When the state of charge reaches a predetermined threshold, the system activates a warning display that alerts the user in advance, allowing them to take avoiding driving operations (such as reducing acceleration demands or preparing to park) before the output limitation is enforced, thus resolving the contradiction between battery protection and user convenience
2Duration of action of stationary object
If output limitation is enforced to protect the battery, then battery life is extended, but driving performance deteriorates due to limited acceleration and power output
Solution Approach 1:
By providing advance warning through the display unit before output limitation is enforced, the system allows users to proactively manage their driving behavior. Users can anticipate the upcoming power restriction and adjust their driving patterns beforehand, potentially reducing the frequency and duration of output limitation events, thereby extending battery life while minimizing the impact on driving performance
3Device complexity
If no pre-notification is provided before output limitation, then system complexity is reduced, but information completeness deteriorates as users lack awareness of impending limitations
Solution Approach 1:
The system implements a preliminary warning mechanism that activates before output limitation occurs. The display unit shows a warning icon at a predetermined state of charge threshold, providing users with advance information about impending power restrictions. This adds minimal complexity to the system while significantly improving information completeness, allowing users to make informed driving decisions
Solution Approach 2:
The warning display acts as an intermediary between the battery state monitoring system and the user. Rather than directly enforcing output limitation without notice, the system uses the display unit as a communication bridge to convey battery status information to the user, enabling them to understand and respond to the battery's charge level before limitations are imposed

AI summary
A vehicle state display device for a vehicle includes an output limiting unit that limits an output of the vehicle when charge of a battery is equal to or smaller than a first value and a battery state display unit that displays a state of the battery. The battery state display unit switches and displays a first display mode indicating that the state of charge of the battery exceeds a second value that is larger than the first value, a second display mode indicating that the state of charge of the battery is equal to or smaller than the second value and exceeds the first value and the output of the vehicle may be limited, and a third display mode indicating that the state of charge of the battery is equal to or smaller than the first value and the output of the vehicle is being limited.
